The principle of the fermionic projector I, introduction and continuum limit

Felix Finster

Abstract:Combining a local gauge principle, the Pauli Exclusion Principle, and the principles of General Relativity in a particular way, we obtain the mathematical framework for the formulation of a new type of variational principle in space-time. The postulate that physics can be formulated within this framework is called the "principle of the fermionic projector."

The principle of the fermionic projector is introduced and discussed. We describe a limiting process with which our variational principles can be analyzed in the setting of relativistic quantum mechanics.
